Combining procedures improves stent expansion in Mount Sinai heart trial

A randomized clinical trial at The Mount Sinai Hospital in New York City showed that combining rotational atherectomy and intravascular lithotripsy before placing a coronary stent improves stent expansion, Newswise reported on November 1, 2026. The dual technique is used to remove calcified nodules in heart patients. According to Newswise, the combined approach increased stent area by 19 percent compared to using intravascular lithotripsy alone. [1]

The procedure targets stubborn calcium deposits inside coronary arteries prior to device insertion. A stent is a tube constructed of metallic alloy or polymer that is inserted into a vessel to keep the passageway open. According to Newswise, fuller stent expansion through the combined techniques leads to improved outcomes for cardiac patients. [1][3]

The Mount Sinai Hospital is a teaching hospital on the Upper East Side of Manhattan that provides specialized medical care. As FTMQ Health reported earlier, researchers in cardiovascular health are also evaluating new dissolvable magnesium scaffolds in European trials to treat extensive coronary artery disease. [4][6]
